Not a big change but effective with the New Year, the filing of a pre-trial statement identifying witnesses for a custody proceeding is, by itself, a certification that the attorney actually spoke to the witnesses listed. The explanatory comment does not tell us much about the origin of the rule, but some litigants like to profess that they are bringing the “world” to testify in a custody proceeding but then that list drops quickly as the day of trial approaches.  Note the certification is not one that you intend to call all of your listed witnesses; only that you at least spoke with them before putting their names in the pretrial statement.  The amendment is Rule 1915.4-4.  It was issued on October 28, 2015.
